In this study, in order to realize ultra compact photonic circuit devices, photonic crystal waveguides with absolute photonic bandgap, which can support both TE and TM waves, are proposed. In these waveguides, single mode propagation is realized for both TE and TM waves. Using these waveguides and magneto photonic materials, nonreciprocal photonic crystal devices are investigated. Furthermore, the optimization method for magneto photonic crystal waveguides is also developed and photonic circulator is designed utilizing it.
